MGL1212 Seismic Reflection/Refraction
Seismic:Reflection:MCS
GeoPRISMS:Funded
Processed multi-channel seismic data from the Cascadia Subduction Zone acquired during the R/V Marcus G. Langseth expedition MGL1212 (2012)
Part of the COAST (Cascadia Open-Access Seismic Transects) project, this 2012 R/V Langseth cruise served as an open-access, open-participation 2D seismic survey of the Cascadia subduction margin off Grays Harbor, Washington, USA, collecting data that will provide background information for siting and planning any future 3D work on this part of the margin. The objectives were to image the plate boundary, to identify downdip variations in the character of subduction thrust associated with seismic rupture, to characterize the subduction interface, and to quantify pore fluid pressure, fluid budgets, and upstream inputs to the ETS zone. Funded by NSF grants OCE-1150628, 1153563, 1147762, 1147841, and 1149095.
